Abstract

This paper embodies the results of field studies conducted on productivity in three different mangrove areas, viz.. Cochin Backwater, Killai Backwater and Andaman Nicobar Islands. The rate of production varied in these areas, but generally indicated a good production rate. The energy inputs from various sources into the ecosystem and the process of conversion are discussed in the light of an
overall energy budget available. The productivity of adjacent marine environments is also discussed in the light of their suitability for development of mariculture practices.
